Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical casting technology, specifically relating to a floating compaction head device for a molding machine. Background Technology
[0002] Vibratory compaction equipment, also known as vibratory compaction molding machine, is mainly used for indoor vibration compaction of cement, lime, and lime-fly ash stabilized granular soil base materials. The equipment includes a CNC program, a power system, a vibratory compaction head, and a compaction mold. The compaction mold is placed under the vibratory compaction head, and the power system drives the head to reciprocate up and down into the mold, compacting the material inside. After compaction, the material needs to be removed from the mold. However, in existing technologies, after the material is compacted inside the mold, the adhesion between the material and the mold wall increases, making it more difficult to remove the material from the mold. This results in difficult and time-consuming operation, uneven sand mold compaction, and a high risk of casting defects such as sand holes, sand inclusions, and mechanical sand adhesion.
